Worst service ever

I went to The Boulders Mall to buy a combo, served by Josiphine(cashier), there was a lady with sky blue t-shirt and st Engenas badge at the couter, the cashier asked if i need sauce, I said yes enough sauce, the guy came from the back screaming at me as if he was drunk or smoked something strong. He said they are tired of customers asking for enough sauce, I must pay extra R5, I asked who is he, he said he's the cone preparing food and the company said he must tell the customers that. He said because I'm talking too much he want to show me, the noise was all over the store, he went at the back and I asked the cashier her name , she said Josephine, I asked if the lady with a badge is the manager, she said yes and she's also a manager. I was surprised and ****ed if staff behave like this in front of the manger, all the lady can say was " you are making noise". I didn't if she was referring to me or the mad guy. What I've learned about this ccompay is they promote women abuse. I didn't eat the food and I didn't ask for refund because I paid with bank card, I just left and threw the food away, I could trust the guy who is confident enough to tell the customer " I will show you"
